Abstract

We report the successful fabrication of single-filament composite MgB₂/stainless-steel ribbons, as an ultrarobust conductor type. The transport critical current of the non-sintered MgB₂/stainless-steel ribbons is remarkably high, as an unexpected result. Transport critical currents I_c ∼ 316 A at T = 4.2 K and I_c ∼ 82 A at T = 20 K were observed at self-field for the non-sintered composite MgB₂/stainless-steel ribbons. The I_c value of 316 A is the higher than any other value reported so far. In addition, the persistent current density, that was estimated by Bean formula, of the sintered composite MgB₂/stainless-steel ribbons was more than J_p ∼ 6 × 10⁵ A/cm² at T = 5 K with H = 0 G, and J_p ∼ 1.1 × 10⁵ A/cm² at T = 30 K with H = 0 G.
